Definitions

  • the present invention relates to a method for producing a medium chain aminocarboxylic acid, and more particularly, to a method for producing a medium chain aminocarboxylic acid from a fatty acid by culturing a recombinant microorganism from which a fatty aldehyde dehydrogenase (or fatty alcohol dehydrogenase) gene in an ⁇ -oxidative metabolism pathway and ⁇ -oxidative metabolism pathway-related genes are deleted and into which an ⁇ -transaminase gene is also introduced.
  • a fatty aldehyde dehydrogenase or fatty alcohol dehydrogenase
  • Bioplatform compounds are produced through biological or chemical conversion on the basis of biomass-derived raw materials, and thus have been used for synthesis of polymeric monomers, new materials, and the like.
  • a medium chain aminocarboxylic acid is a material used as a monomer for polyamides.
  • the polyamides are classified into aliphatic polyamides, aromatic polyamides, and aliphatic cyclic polyamides.
  • Representative examples of the aliphatic polyamides includes Nylon 12, Nylon 6, and Nylon 66, and the aromatic polyamides have an aromatic framework introduced therein in order to further improve heat resistance, and are also known under the name of aramid.
  • nylon is a representative engineering plastic material whose demand and use have increased steadily due to high crystallinity, mechanical strength and thermal stability, excellent wear/friction resistance characteristics, and the like. Also, there has been continuous research conducted in various fields to improve the thermal and mechanical properties of nylon. Among theses, there is research conducted to impregnate wax and graphite so as to improve wear resistance of nylon. In addition, there is ongoing research conducted to improve the physical properties of nylon through the crosslinking of polymers.
  • Nylon 12 synthesized through the polycondensation of 12-aminododecanoic acid exhibits low specific gravity, excellent low-temperature characteristics and wear resistance and high weather resistance due to the insignificant effects of ultraviolet rays, and also has a very short -CH 2 - chain length, compared to other nylon resins (i.e., Nylons 6, 66).
  • Nylon 12 has a low probability of having a hydrogen bond of H 2 O to an amide functional group when present in the same weight, Nylon 12 may serve to prevent the degradation of mechanical strength caused by moisture absorption, which is one of the biggest drawbacks of the nylon resins, which makes it possible to widely apply it to materials for automobile parts, aircraft materials, heat-resistant special fibers, and the like ( Beomsik, Shin, et al., Polymer, 35(1):30-34, 2011 ).
  • Production of medium chain aminocarboxylic acids such as 12-aminododecanoic acid may be carried out using biological methods through chemical synthesis or microbial fermentation.

  • ⁇ -oxidation refers to a metabolic process in which the terminal methyl group of a fatty acid is oxidized to form dicarboxylic acid
  • ⁇ -oxidation refers to a metabolic process in which a carbon atom at the ⁇ -position in a carboxyl group is oxidized to release acetyl-CoA, whereby fatty acids are gradually decomposed into fatty acids whose number of carbon atoms is reduced by two.
  • the concept of the ⁇ - and ⁇ -oxidations and the enzymes involved in such metabolic processes are widely known to persons having ordinary skill in the field of biochemistry.
  • an ⁇ -hydroxy fatty acid is first produced by means of an action of cytochrome P450 and an NADPH-cytochrome P450 reductase. Then, the ⁇ -hydroxy fatty acid is converted into ⁇ -aldehyde fatty acid by an action of a fatty alcohol dehydrogenase and a fatty alcohol oxidase, and the ⁇ -aldehyde fatty acid is converted into dicarboxylic acid by an action of a fatty aldehyde dehydrogenase. Also, for the ⁇ -oxidation, a fatty acid whose number of carbon atoms is reduced by two is produced by an acyl-CoA oxidase (see FIG. 1 ).
  • Transaminase (TA, EC 2.6.1.X) is an enzyme which exists widely in nature and is involved in the transfer of an amine group in the nitrogen metabolism of an organism. Generally, transaminases serve to remove an amino group from one amino acid to transfer the amino group to another ⁇ -keto acid. The transaminases are used to produce optically pure non-natural amino acids and amine compounds because the transaminases have various outstanding advantages in that they exhibit wide specificity to substrates, high optical selectivity, a rapid reaction rate, and superior stability, and have no need for reproduction of coenzymes, and the like. The transaminases may be classified into five groups depending on the structures and multisequence alignments of proteins found in the Pfam database.

  • the ⁇ -transaminases may be used as enzymes very useful for production of optically active amine compounds.
  • the ⁇ -transaminases were first employed at 1990 by Celgene Co. (USA) to synthesize chiral amines.
  • the ⁇ -transaminases have been importantly employed for studies on asymmetric synthesis of chiral amines and studies on improvement of kinetic resolution.
  • Evonik Industries AG Germany reported one case in which 12-oxolauric acid methyl ester is converted into 12-aminolauric acid methyl ester using an ⁇ -transaminase of a Chromobacterium violaceum DSM30191 strain.

Also, a PCR process was again performed using the primers listed in Table 2 to check whether the ura3 gene was deleted from the strains. A knock-out process was performed on other genes of the Ura3-free strains.
  • Example 4 Culturing of recombinant microorganism strain
  • the strain to be cultured and tested was inoculated in 2 mL of an YPD medium (Bacto Laboratories, 10 g/L of Yeast extract, 20 g/L of peptone, and 20 g/L of glucose), and grown at 30 °C and 200 rpm for a day.
  • 2 mL of a growth medium (pH 6.0) having the compositions listed in Table 7 was put into a 24-well plate, and a pre-cultured culture broth was inoculated at 1%. Thereafter, the strains were cultured at 30 °C and 450 rpm for a day in a plate stirrer.
  • the strains cultured for a day were inoculated at a volume of 900 ⁇ L in a new plate containing 900 ⁇ L of a conversion medium (pH 7.6) listed in Table 8, and 200 ⁇ L of a substrate was added thereto at the same time.
  • the resulting mixture was cultured at 30 °C and 450 rpm for a day.
  • 10 g/L of dodecanoic acid dissolved in DMSO was used as the substrate.
  • the Y2-36 strain exhibited an ability to synthesize approximately 8 mg/L of 12-aminododecanoic acid when cultured in the flask ( FIG. 8 ).
  • a sample analysis test was performed using the Y2-36 strain.
